The Pew Forum on Religion & Public Life provides a portal into their data on all questions of religion and politics in the scope of the upcoming 2012 presidential election. Visit the site here.
The most recent analysis breaks down the preference of religious voters for the current crop of GOP candidates. Perhaps unsurprisingly, Gov. Mitt Romney enjoys a comfortable lead over all his opponents with Catholic voters, while he barely leads or trails behind others with Evangelical and mainline Protestant voters. Romney appears to be the most centrist top-tier candidate in the field, and Catholic voters in general tend to be more centrist in their voting patterns than Evangelicals. Could this account for these findings?
In a hypothetical matchup against President Obama, Catholic voters slightly prefer Romney over Obama, and if Gov. Rick Perry were the nominee, Catholic voters would go for the President.
